An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86219 in the wild and no public exploit code.\n\nAffected product: perl-Authen-SASL. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-86219/ (Markdown: https://insights.sbomify.com/CVE-2026-86219/index.md)","id":"CVE-2026-86219","markdown":"https://insights.sbomify.com/CVE-2026-86219/index.md","name":"CVE-2026-86219","record":{"aliases":["BELL-CVE-2026-86219","DEBIAN-CVE-2026-86219","GHSA-w4h4-7ff5-56xr","MGASA-2026-0400","OESA-2026-3775","OESA-2026-3776","OESA-2026-3778","OESA-2026-4004","ROOT-OS-DEBIAN-12-CVE-2026-86219","SUSE-SU-2026:23913-1","SUSE-SU-2026:4280-1","SUSE-SU-2026:4302-1","UBUNTU-CVE-2026-86219","USN-8858-1","openSUSE-SU-2026:11734-1","openSUSE-SU-2026:21946-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl SASL library","requires_auth":"none","summary":"Attackers can replay captured authentication responses to bypass password verification and impersonate users in Perl SASL DIGEST-MD5 implementations.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"Authen::SASL::Perl::DIGEST_MD5 versions before 2.2100 for Perl accept replayed authentication responses via unverified nonce in server_step.\n\nserver_start generates a fresh nonce and sends it in the challenge, and nothing later compares that value against the nonce the client returns. server_step derives the expected digest from the client's own parameters, so a response verifies whenever its digest matches the nonce it carries. The count table it also checks is keyed on the client-supplied nonce and starts empty in each new server object, so a captured first response, carrying `nc=00000001`, passes that too. RFC 2831 defines the nonce in the response as the value the server sent in the preceding challenge.\n\nAn attacker who observes one successful `qop=auth` exchange can replay the captured response against a later session for the same service, host, realm and user, and authenticate as that user without knowing the password.","ecosystems":["SUSE:Linux Enterprise High Performance Computing 15
